Like X means "not X but something that resembles X."
This is often used in mid-sentence to emphasize that X is an exaggeration or guess.
It can also be used if the speaker (and hopefully not writer) doesn't know exactly what words to select for something but instead uses words that come to mind immediately or that he/she thinks you would prefer.
I was talking to that like Dracula guy over there, that one that looks like he's a vampire or whatever.
These uses can combine and sometimes be used to express politeness in a weird way.
You are like the best dressed person I've ever seen in my life.
So I went to court and I told the judge, "I like, totally respect you and stuff." (Probably would still go to jail.)
I think this movie is responsible for causing this to become common.
